This heat is flex'n the power grid like mad ATM!! Since about 1pm the 13.2kva primary feeders have been sagging by about 6-12inches which is allot. The high tension 100kva must be sagging by over a foot. Serious capacitor demand also with the amount of AC use. This is when **** starts blowing up. When you get 95 degree day readings like this and warm nights things explode.

Starting to get some much needed shade from building cumulus clouds. Probably nearing the high temperature for the day. 92°.

SpartyOn: Are you looking at the high tension lines? The small typical ones here are fine.

Interesting.... I have never thought of looking at the power lines on a hot day, makes sense that the heat would cause this though.

Both primary 13.2 lines and the high tension 100+kva lines are sagging. Its common for power lines to sag under high load and heat. Its the running of AC units that cause the high loads. The great American blackout of 03 was a by product of sagging lines east of CLE. They arced out on trees and boom went the entire grid.

On days like today it's the substations that are really and literally humming. Row after row of capacitors at almost full throttle. A good friend o mine is a sub station tech and Ive been told that on high load days within the station your arm hair will stand on end because of the EMI. Cool stuff indeed.

Anyways kind of leveled out 91-92 here.

Once again Lake Michigan ftw, at least 10 degrees cooler than a few miles inland

I am watching the Carthage College site, only 69° there right now! Lake breeze might try to push inland as we get later in the day and the onshore winds die off.

93.7° here.

I noticed the Quad Cities area is not any hotter then yesterday! Higher soil moisture the culprit?

Could be. This area really isn't all that dry. MLI is only down 2.50" for the year, which isn't bad at all considering the bone dry winter. Every time the grass starts to brown up we get a decent rain within a week it seems.
